How many birds appear at different times of day?

introduction:

There are many birds and I thought that there would be a different number of birds at different times of day. I think that there would be more birds during the night then in the morning or afternoon. I think that there are more in the night but are harder to see and

Hypothesis:I think that birds will show up more in the night because there are less predators around.

procedure:

• Fill up bird feeder with sunflower seeds.
• watch birds from 7-7:30 am and count the number of birds that appear.
• Refill bird feeder with sunflower seeds.
• Watch birds from 12-12:30 pm and count the number of birds that appear.
• Refill bird seeder with sunflower seeds.
• watch birds from 5- 5:30 and count the number of birds that appear.
• continue for 5 days.

observations:

During the First day, there weren't many birds that came to the feeder.

materials: bird seeds, bird seeder.

Independent variable: Time of day.

Dependent variable: Number of birds that appear at feeder.


Results and Data:

day 1-5	7-7:30 am	12-12:30 pm	5-5:30 pm
First day	3 birds	2 birds	1 bird
second day	4 birds	4 birds	3 birds
third day	2 birds	3 birds	4 of birds
fourth day	5 birds	6 birds	2 birds
fifth day	3 birds	1 bird	5 birds
end of project	avg. 3.4 birds	avg.3.2 birds	avg.3 birds

Conclusion: There was a small number of birds out during my project. I think that the whether affected the number of birds that came to my feeder. The average of the birds showing up at different times were very similar but I think that if this was done when there were more birds and I observed for a longer time, it would change a lot.
